Title: Hydrocarbon(s) conversion and aromatic hydrocarbon(s) prodn. - in presence of hydrogen in series of reaction zones, followed by regeneration of catalyst
Inventor: MACAIRE JEAN-CLAUDE
IPC: C10G35/12
Filed: 1991-01-10
Abstract: In conversion of hydrocarbons or recovery of aromatic hydrocarbons in presence of a catalyst through which a feed contg. hydrocarbons and H2 circulates, in reaction zones connected in series, and which forms a flowing bed, the feed passes successively through the zones and the catalyst passes downwards through the zones, is removed from the bottom of each zone except the last and is fed in a current of H2 to the head of the next zone, is removed continuously from the bottom of the last zone and is fed to a regeneration zone.  The exhausted catalyst removed from the last zone is freed from H2, and is fed into an inert gas, in which it is led into a regeneration zone by means of 2 transporters; the 1st transporter feeds the catalyst from the reaction zone into a container at a higher level, from which the catalyst passes continuously through a downward pipe into a lower container; the 2nd transporter feeds the catalyst from the lower container into a supply vessel in the upper part of the reaction zone. USE/ADVANTAGE - Process is esp. the hydro-reforming of hydrocarbons, e.g. a naphtha boiling at 60-220 deg.C, or the prodn. of aromatic hydrocarbons, esp. benzene, toluene and xylene. Method gives improved equilibrium between the catalyst circulation by means of blow-off valves, above the regenerator and the intermediate container, and avoids blockage by catalyst particles.

Patent DE-4121757-A1 (DE)
Inventor: BURI GERHARD
IPC: F16H3/78
Filed: 1991-07-01
Abstract: In a range change gearbox of the planetary gear type (2) for vehicles, a sun wheel (3) is driven by an output shaft from a main gearbox, a planet carrier (8) being rigidly connected in rotation with an output shaft (9) of the range change gearbox.

Patent DE-4207112-A1 (DE)
Inventor: STUMPF HEINRICH
IPC: G01J5/08
Filed: 1992-03-06
Abstract: A Fresnel lens produced by appropriate embossment of a plastic film is normally used to focus the thermal radiation to be fed to an infrared motion detector. The Fresnel lens, which is to be arranged in the shape of an arc above the infrared detector, is provided with a frame in order to achieve an adequate dimensional stability. The frame is injection-coated in order to join it to the film, but as a relatively expensive manufacturing operation this deserves to be improved. According to the invention, the Fresnel lens (1) provided with a frame is produced of one material as an injection-moulded part, and the two longitudinal webs (6) of the frame of the Fresnel lens (1) which are to be inserted into frame pockets of the device housing are tapered in the direction of insertion in such a way that they are adapted in a sealing fashion to the lifting-out inclination inside the frame pocket. <IMAGE>
